document.write( "Question 557308: Factor 81r^6-3p^6. I started off finding the greatest common factor which is 3. Here is what I have so far, I hope it makes sense as I am following an example from my notes. 3(27r^6-p^6) The exponents are a difference of cubes so, 3(27r^2)^3-(p^2)^3. This is where I get confused...Is 729r^4+27r^2p^2+p^4 the correct next step and how do I solve it from here? This is due today. Thank you so much \n" ); document.write( "
